Can I find this ? A report from my QB online account that listed each login-logout time and the related description of the transaction.

The log in and log out time history can be found in the Audit Log report, dmasonqb.

It also list the event or type of transaction that was added, edited, or deleted in your account. Here's how to open it:

1. Go to the Gear icon ⚙and select Audit Log.
2. Click Filter.
3. Click the drop-down list for Filter and choose the appropriate User, Date, or Events filter to narrow the results.
4. Select Apply.

You can also click the View link under the History column to see more details about the data entry. It's where you can see the description of the transaction. Here's an article about using the Audit Log for more details about this feature: Use The Audit Log In QuickBooks Online.
